That's because the Klackeberga church is using the durable bags to store the remains of around 80 people who were once buried under the floorboards.

They were dug up when parts of the church were remodelled to allow wheelchair access.

"There were loads of skulls and bones stuffed into Ikea bags. I counted up to 80," Kicki Karlen told the Expressen newspaper.

"I became angry, very angry about how they were just sitting there. I spoke with some people from the parish who said the bones had been there since 2009."

An archaeologist who helped dug out the bones five years back is mystified as to why the bagged bones have been gathering dust all these years Ludvig Papmehl-Dufay told The Local.

"Our mission was to document and rebury the bones, which may be as much as 500 years old. But the reburial was delayed and I have no idea why. The plan was to rebury them as soon as possible, but that's up to the church. The county board said they couldn't leave church ground, and it became complicated."

Papmehl-Dufay did, however, see the beauty of the handy bags.

"The Ikea bags aren't actually that bad. They'd be great for stopping the moulding process. But it can't be that good to have them in the basement for so long."
